对水的需求不断增加和自然水资源的枯竭，以及目前的环境问题，导致需要提供更多的水，以加强水资源和生态系统的可持续性。集水技术是解决这一问题最有效的方法之一。本研究采用基于地理信息系统的多准则分析和模糊逻辑模型，确定了迪亚拉流域雨水收集的适宜区域。选择了七个标准：坡度、河流顺序、降雨、径流、水文土壤类型、土地利用和与道路的距离。将适宜性划分为“非常低”到“非常高”的5类，适宜性图显示，高适宜性区大部分位于研究区东南部，低适宜性区大部分位于西部和北部。最后，本研究将有助于在更大范围内进行有效的雨水规划和管理。
The rising demand for water and the depletion of natural water resources, as well as the current environmental problems, have led to the need for the provision of additional quantities of water to enhance water resources and the sustainability of ecosystems. Water harvesting technologies are one of the most effective solutions to treat this issue. In this study, appropriate zones for rainwater harvesting in the Diyala Watershed were identified using the Geographic Information Systems-based multi-criteria analysis and fuzzy logic model. Seven criteria were selected: slope, stream order, rainfall, runoff, hydrological soil group, land use, and distance to roads. The map of suitability was categorized into five categories, ranging from very low to very high, and the map showed that the majority of high-suitability areas are situated in the southeast parts of the study area, while most of the regions of low suitability are located in the western and northern parts. Lastly, this study will contribute to the effective planning and administration of rainwater on a broader scale.
